According to the difficulties in beneficiation, such as intimate dissemination and complicated intergrowth of pentlandite, chalcopyrite and pyrrhotite, and high content of magnesium-bearing silicate minerals, a beneficiation experiment was conducted for a low-grade copper-nickel sulfide ore from abroad. A flowsheet consisting of rough grinding, fine-grinding of middlings, copper-nickel bulk flotation was introduced to treat this raw ore with Ni and Cu grades respectively as 0.50% and 0.20%. Adopting selective grinding approach and using high-efficient depressant CMC, excessive comminution of copper and nickel minerals can be avoided while magnesium-bearing silicate minerals can be selectively depressed. A closed-circuit test produced a copper-nickel concentrate grading 9.70% Ni and 4.75% Cu at corresponding recoveries of 68.99% and 79.85%, indicating copper and nickel resources were all effectively recovered.
